Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)
Summary
Simon Willison discusses the MCP 2.0 stateless specification, arguing it simplifies client and server implementations and improves scalability. He compares stateless MCP to the legacy, highlights security considerations around offering shell access to agents, and showcases OSS tooling (mcp-explorer, datasette-mcp, llm-mcp-client) and practical usage examples. He connects this update to ongoing AI tool integration and safer agent design.
